So it sounds like the consensus is that I should not worry about using slices with ZFS and the swap best practice doesn't really apply to my situation of a 4 disk x4200.
So in summary(please confirm) this is what we are saying is a safe bet for using in a highly available production environment? With 4x73 gig disks yielding 70GB each: 5GB for root which is UFS and mirrored 4 ways using SVM. 8GB for swap which is raw and mirrored across first two disks (optional: or no liveupgrade and 4 way mirror this swap partition) 8GB for LiveUpgrade which is mirrored across the third and fourth two disks This leaves 57GB of free space on each of the 4 disks in slices One zfs pool will be created containing the 4 slices the first two slices will be used in a zmirror yielding 57GB The last two slices will be used in a zmirror yielding 57GB Then a zstripe (raid0) will be layed over the two zmirrors yielding 114GB usable space while able to sustain any 2 drives failing without a loss in data Thanks P.S. Availability is determined by using a synthetic SLA monitor that operates on 2 minute cycles evaluating against a VIP by an external third party. If there are no errors in the report for the month we hit 100%, I think even one error (due to the 2 minute window) puts us below 6 9's..so we basically have a zero tolerance standard to hit the sla and not get penalized monetarily This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
